Postman Monitor / error : getaddrinfo ENOTFOUND - postman

I'm configuring Postman Monitor to schedule night executions.
However I'm facing the following error in the monitor console log:
Error: getaddrinfo ENOTFOUND ...
Note that I'm working on the private network of my company.
When I send the request manually without the monitor it is working fine.
Could you please help me to fix this issue?

It is possible that in the header the server responds with a different name than the one you put in the URL. The name must also be resolvable by DNS or hosts file

Testing Grafana alert returns "Failed to test the rule" with 500 - Internal Server Error response

I'm trying to set up alerts on one of my graphs. I'm using AMG (Amazon Managed Grafana). However, I'm getting "Failed to test the rule" notification. When I inspect HTTP response, it shows
Status Code: 500 Internal Server Error
{"message":"Failed to test rule"}
URL
https://g-39e1d60d36.grafana-workspace.us-east-1.amazonaws.com/api/alerts/test
Here is my alert setup (even If I try something super simple, still getting the same issue):
To me, it seems like Grafana internal error/bug, does anyone experience a similar issue and know the potential resolution?
For us the solution was to not set the datasource dynamically from the environment variable we added in the interface. When we moved the target query to a fixed datasource, it all worked ok.

Unhandled Exception: SocketException: Failed host lookup: (OS Error: No address associated with hostname, errno = 7)

we already have a release version in playstore and its working just fine.
But suddenly now when we try to build and run the code again since we want to add new functionality. It would no longer communicate with our backend.
So i searched the net using the error as keyword and saw that need INTERNET PERMISSION as the 100% result and answer, which we have already and not helpful at all. Yes we have it in debug and live manifests.
The server is up we can access it in the browser and as well as postman also dig command
So i searched more things in the net to no avail, found about the because proxy issue thing i tried both client side and server-side. we don't have proxy
we use simple request only like this:
static Future getDriver(String phone){
var url = baseUrl + "/mobile/driverPhone";
return http.post(url,body: {
"phone" : phone
});
}
also some suggestion say to use DIO, but i want to know the reason first before i gave up with this http plugin. Can someone with good heart explain and help me with this?
P.S. we on master channel, here are some error logs
The error SocketException: Failed host lookup: 'api.xyz.com' (OS Error: No address associated with hostname, errno = 7) usually means that your DNS lookup fails. From the error itself OS Error, is usually a system-level error and nothing specific to http or Dart/Flutter.
You might need to adjust some settings in your DNS. Also, if you are using a Mac/Linux system you might be able to run dig api.xyz.com to see if that resolves.
Running your app in the actual device could be possible as well since there is a possibility its getting an error in your virtual device due to DNS settings or the virtual device you are using is not connected to the internet. You will be able to isolate the problem.

Route53 Domain Transfer - Registry error - 2400 : Command failed (421 SESSION TIMEOUT)

I am trying to transfer a domain using Route53 and after a few minutes I receive an email with the following error.
Registry error - 2400 : Command failed (421 SESSION TIMEOUT)
Anyone have any ideas what this means or how to get around it?
I have never seen your error. There is a document on transferring domains with error messages. The reason that I am responding is that I have seen domain transfers fail going to Route 53 without every learning why they failed. Maybe this will help you.

AWS Lambda cloudwatch logs throw "Failed to load events" error

I have a lambda function with the following permissions
whenever the lambda function is triggered, I see a log file being added to the logstream in cloudwatch.
When I try to open any of the logs, it throws Failed to load events
Unexpected error loading events error. Please help with fixing the issue.
I had the same error. The issue was: my 'Authorization' header has been modified. In my case — I added it using chrome extension for the testing purposes
For what it's worth, I saw the same error using Firefox but got the expected results using Chrome. So use Chrome to view CloudWatch.
This just happened to me. I suspect it had something to do with AWS's recent DNS issues. I had to go into my router's settings and change from dynamic DNS to static DNS. I used servers 1.0.0.1 and 1.1.1.1. Hope this helps someone!
